Patented June as, 1909.

Application filled July 9, i867. time! No. 382,888.

To all whom it may concern:

Be it known that I, HANS RIBS, a citizen of the Empire of Germany, residing at Munich, German have invented certam new and useful In rovements in Gas-Retort Furnaces an I do hereby declare the following to be a full, clear, and exact description of the Invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to retort furnaces speclall suitable for the manufacture of coal gas an particularly to furnaces of-the type having inclined chambers or retorts'which are char ed from the rear. This method of chargm is, for instance, required in cases where t ere are two or more super osed series of chambers so that the lower we is of the up r chambers form the roofs or upper wa 50f. the chambers situated below them.

,The object of the invention is to enable the chambers to be com letely charged u to their-roof and to regu ate the heating 0 the chamberssuch a manner that not only is them-which collects in the upper portion of a chcrnberevented from'becoming decomposed but I o the bottom of the chamber sufiicientlyiheated without providing heal ingcondults in it. A construction of furnace is illustrated in the drawings, in which,

' Figure 1 is a vertical longitudinal section of the furnace on line 1-1 of Fi 2, Fig. 2 is a verticclsection on line 22 of ig. 1, Fig. 3 a vertical longitudinal section through the ilpper portion of the furnace on line 33 of 1g..2, and Fig. 4 shows one half of a horizontal cross-section on line 44 of Fig. 3.

As will be seen from the drawing, the roofs b of the chambers or retorts a are formed higher at the upper ends of the chambers so that an additional ace 0 is formed in the up er part of the chamber above the line fol owed'by the greater part of the roof 1). Into this widened portion 0 opens the laterally arranged charging shalt (Z through which the coal or other material to be distilled is fed. Owing to the arrangement of the widened ortion c in the highest portion of the charm ers a it is ossible to fill the chamhers completely wit the material which is introduced in an: oblique direction through the charging shaft d. T he space 0 is also used as gas collecting s acc to which a rising or ascension pipe (not s iown in the drawing) 7 for discharging the gas is connected.

When the lateral walls and roof of the chamber a are heated in a uniform manner, the space c is at the same temperature as the other walls. This is disadvantageous since the heavy hydrocarbons of the gas generated become decomposed by the hot walls of the collecting space 0. avoid as far as possible such decomposition of thegas in the interior of the space c, the conduits for the heating gases are arranged in the following manner. The chambers a which are arranged side by side (three are shown in the exam dc illustrated) are separated from each oti or by the vertical dues or conduits c and and from the lateral walls 9 and h of the furnace, by the vertical fines i and j. The fiues e and i and f and y are connected together at the top by transverse roof conduits 7:. As will be seen in Fig. 1, these roof conduits l? are, however,

arranged only in the lower and central portions of the roof 6, while the lateral conduits eft' j adjoining the upper portion of the roof t are connected to conduits it provided in the back wall at of the furnace which at the same time is the rear wall, of retort. This connection is eil'ected by providing the partitions in the upper portion of the dues e f i j adjoining the space 0, with perforations 0 which connect these lines to the conduits 'n (Figs. 3 and 4) provided in the back wall m. Owing to this method of conducting the heating gases, a direct heating of the gas collecting space 0 is avoided, and thus a decomposition of the gas collecting in that s ace obviated, and also the back wall m of t ic furnace is in that way heated directl so that coals resting against it are completely distilled.

The lateral walls of the furnace chambers a rest upon laterally projecting bottom walls or stones 'p carried )y vertical pillars T which preferably extend down to the foundations of the furnace so that the weight of the chambers a and of their charge is transmitted direct to the foundations. I

Below the bottom walls 1) supporting the chambers a on the pillars r are arranged conduits s for heating gases separated by a partition u from air conduits t. The part1- tion a terminates immediately below the ,1 rojecting portion of the lower walls 11. Eonscquently the combustion of the heat ng gases takes place in the space laterally hmited by the bottom wall p above the free end of the partition to, so that at thatpoint in order. to

is situated the hottest combustion zone, the

heat of which is transmitted by the'bottom walls p to the bottom ofpthe chambers a. in that way the bottoms of the chambers'a 5 are heated to a sufiicient extent without it being necessary to arrange heating conduits inthem-which greatly affect the durability a Y e air'for combustion carriedjin the con 23 0 duits t-is subjected in Well known'manner to preliminary heating bi; means of the re, generator arranged no t e bottom portion of the furnace, which receivesits heat; from the gaseswhich esca e from the condits i 7'. Q Constructiona details of the-furnace d8". scribed can of course be modified according to different circumstances without departing,

from the spirit of the invention, for instance two or more series of furnace chambers can be arranged above each other, so that the roof of one series of chambers forms the bot tom'of the one immediately above" it.
